If you enable this policy, the Profile Storage Space dialog is displayed when a user logs off if their profile exceeds the maximum size.
When this occurs, they are required to reduce their profile size before they can log off.

Welcome to the Windows Vista Security Guide.
This guide provides instructions and recommendations to help strengthen the security of desktop and laptop computers running Windows Vista
in a domain with the Active Directory directory service.

The host (A) records for one or more clients contain incorrect IP address, preventing name resolution, when a Windows Server 2003 DHCP
(Dynamic Host Configuration Protocol) server is configured to update A records and PTR records in DNS.

This behavior can occur if there is no reverse lookup zone for the IP subnet, or if the reverse lookup zone is not configured to allow dynamic updates.

The Lsass.exe (Local Security Authentication Server) process on your Windows Server 2003 domain controller may hang if you have many
external trusts and many simultaneous logon requests that do not specify the domain name.

This behavior will occur because the Lsass.exe process runs out of resources if the 'number of simultaneous logons' multiplied
by the 'number of trusts' is grater than 1,000.

Windows Vista allows you to create multiple local GPOs. You can create them for any user, by name, for all the members of the local Administrators group, and for all users who are NOT members of the local Administrators group.

When a user logs on, their registry profile atHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\<SID> contains a State Value Name,
a REG_DWORD data type, that is a bit mask whose value indicates the state of the local profile cache.
